In subject area: Computer Science A clock interrupt is a type of interrupt that occurs periodically in a system, but can be disabled to prevent interruptions during critical sections of code. AI generated definition based on: DSP Software Development Techniques for Embedded and Real-Time Systems, ...
to signal critical events or errors. these internal irqs are essential for system stability and error handling. what do i mean by cascading irqs in computer systems? cascading irqs involve using one irq line to manage several irqs simultaneously. in older systems with limited irq lines, this ...
The FastWake system architecture is compatible with existing RDMA applications, operating systems, and hardware. We added the ODPI preload library as a shim layer in the user space. We updated the OFED kernel modules to shorten the kernel path and added a “switch_to“ system call to implement...
You can easily end up with more devices in your computer than there are inter- rupts. If a module requests an IRQ at initialization, it prevents any other driver from using the interrupt, even if the device holding it is never used. Requesting the interrupt at device open, on the other...
model, in a FPGA architecture. Finally, in Section 7, conclusions are presented. 2. Difficulties of the traditional model in real-time systems Since the traditional model of interrupt handling is strongly supported by hardware, it yields a fast ...
In 2000 - when I was helping the Computer History Museum restore their 1620 by designing and building a hardware peripheral emulator - I had the honor of discussing it with the late Joe Crespo, an IBM engineer from the San Jose group that brought up the prototype in 1958. He told me tha...
The first computer to provide interrupts was probably the UNIVAC 1103A (1956). The book "Computer Architecture" by Blaauw and Brooks discusses different approaches to interrupts in great detail, pages 418-434. A history of interrupts is inthis article.↩ ...

One interconnect fabric architecture includes the Peripheral Component Interconnect (PCI) Express (PCIe) architecture. A goal of PCIe is to enable components and devices from different vendors to inter-operate in an open architecture, spanning multiple market segments; Clients (Desktops and Mobile), Se...
